Despite these tax-avoidance shenanigans, I think they do pay tax in Ireland, just a ridiculously small amount.

And not just Google I believe Apple laundered north of 50 billion and only have a handful of employees here http://www.nytimes.com/2012/04/29/business/apples-tax-strate...
As a small business owner it sickens me with how these large companies can get away with so much here, ok granted they are creating jobs (badly needed) and have other positive effects on a sinking economy but having Revenue put a blind eye on these shenanigans while making life miserable for small companies is unfair.
